Salads
This Mrs Gerry's potato salad copycat recipe delivers the same vinegar-kissed crunch and creamy perfection that made it a picnic staple for generations. The secret lies in precise boiling and a tangy dressing blend that balances sweet and sharp flavors—just like the original.
I've perfected this method over years of testing, ensuring every bite stays creamy yet slightly crisp at the edges.
The process begins with waxy potatoes boiled until tender but still holding their shape, then cooled before cutting. A foolproof dressing combines mayo, mustard, apple cider vinegar, and a pinch of celery seed for that signature tang.
The key to authenticity is letting the salad chill for at least 4 hours—this allows flavors to meld and the vinegar to develop its signature bite.
What you'll end up with is a classic potato salad that's creamy yet textured, with just the right amount of crunch from diced celery and onions. The vinegar-kissed dressing cuts through the richness, creating a perfect balance that makes this dish a picnic favorite.

Serve with grilled chicken, ham, or as a standalone side—this potato salad is the centerpiece of any summer spread. The chilling time ensures maximum flavor development, so plan ahead for the best results. Let's get started on recreating this timeless classic!
Ingredients for mrs gerry's potato salad copycat
Classic picnic flavors start with these simple, quality ingredients for perfect potato salad.
| Ingredient | Amount | Notes |
|---|---|---|
| Yukon Gold Potatoes 🥔 | 2 lbs | Waxy variety, cut into 1-inch cubes |
| Mayonnaise 🥛 | 1 ½ cups | Dijon-style preferred for tang |
| Yellow Onion 🧅 | 1 whole | Medium size, finely diced |
| Celery Stalks 🌿 | 3 whole | Stringless, finely diced |
| Apple Cider Vinegar 🍎 | ¼ cup | Unfiltered for authentic bite |
| Dijon Mustard 🍯 | 1 tbsp | For proper tang balance |
| Celery Seed 🌿 | ½ tsp | Ground for signature flavor |
| Salt 🧂 | 1 ½ tsp | Kosher or sea salt |
| Black Pepper 🌶️ | ½ tsp | Freshly ground preferred |
| Granulated Sugar 🍚 | 1 tbsp | Balances vinegar tang |
| Hard-Boiled Eggs 🥚 | 4 whole | Chopped for classic texture |
| Fresh Dill 🌿 | ¼ cup | Chopped, optional garnish |
The potatoes are non-negotiable—Yukon Golds deliver that signature creamy texture without turning gluey. Whole Foods or Trader Joe's carry them year-round, but any waxy variety (red potatoes work too) will do. For the dressing, Dijon-style mayo adds depth—Hellmann's Classic or Best Foods are foolproof choices. The vinegar should be unfiltered apple cider (like Mott's) for that authentic bite. Celery seed is key—Penzeys sells it in bulk if your grocery store doesn't carry it.
No Dijon mayo? Regular mayo plus 1 tsp prepared mustard works in a pinch. Short on celery seed? Substitute 1/4 tsp ground caraway for a similar earthy note. The sugar balances the vinegar—brown sugar works too—but don't skip it entirely. For the eggs, ice-cold water bath makes peeling easier. Fresh dill is optional but adds that bright, herby finish that elevates this from basic to restaurant-quality. The onions and celery should be finely diced—smaller than 1/8-inch for that perfect crunch.
Potatoes keep best in the fridge for 3-4 days after boiling—cool them completely before cutting to prevent mushiness. The dressing can be made 2 days ahead and stored separately. Once combined, this salad tastes even better after 6-8 hours chilling—the vinegar develops its signature tang. For picnics, pack it in a glass container with a tight lid to maintain texture. Leftovers? Refrigerate for up to 5 days—it reheats beautifully for sandwiches.
Why You'll Love This Recipe
- No Boil, No Stress: I swear by the cold-water soak method—just slice those Yukon Golds, let them sit in ice water for 10 minutes, and they stay perfectly firm. No waiting for a pot to boil, no mushy disasters. Honestly, this is the only way I make potato salad now.
- Tangy Creamy Magic: That apple cider vinegar cut isn’t just a splash—it’s the secret. It brightens the mayo so the salad tastes fresh, not heavy, and the onions? They caramelize just enough to add this unexpected depth. Between us, it’s the closest I’ve gotten to the real deal.
- Picnic to Potluck: This recipe works everywhere—pack it in a mason jar for a beach day, bring it to a BBQ where everyone else’s potato salad is sad, or just eat it straight from the bowl with a fork. (Yes, I’ve done that.) It’s the kind of dish that disappears fast, no matter the occasion.
- Leftovers? Better Than Fresh: Between us, the flavor improves overnight. The potatoes soak up the dressing like a sponge, and the celery stays crisp. I make a double batch on Sundays, and by Wednesday, it’s still the star of my lunch. Budget-friendly? Absolutely. Waste-free? Even better.
Step-by-step instructions for Mrs Gerry's potato salad copycat recipe
Here's the exact method to recreate that iconic picnic potato salad with tangy crunch and creamy texture.
Boil and Cool the Potatoes
Place the 2 lbs Yukon Gold Potatoes in a large pot and cover with cold water by about 2 inches. Add 1.5 tsp of the salt and bring to a boil over high heat. Once boiling, reduce heat to medium and cook for exactly 10 minutes until the potatoes are tender but still hold their shape when pierced with a fork.
Drain immediately and transfer the potatoes to a large bowl. Let them cool for 10 minutes before handling - this prevents them from breaking apart when chopped. I find this cooling step essential for maintaining the potato's structure in the final salad.
Prepare the Dressing Components
In a medium bowl, whisk together the 1.5 cups mayonnaise, 0.25 cup apple cider vinegar, 1 tbsp Dijon mustard, 1 tbsp granulated sugar, 0.5 tsp celery seed, 0.5 tsp black pepper, and the remaining 0.5 tsp salt. The mixture should be smooth with no visible streaks of mustard. This is the foundation of the dressing that gives Mrs Gerry's salad its signature tangy-sweet balance.
Taste the dressing before combining with the potatoes. It should be pleasantly acidic with a hint of sweetness. If needed, adjust with a touch more vinegar for tang or sugar for sweetness. The dressing should coat the back of a spoon without being overly thick.
Chop Vegetables and Mix with Potatoes
While the potatoes cool, finely dice the 1 whole yellow onion and 3 whole celery stalks. I like to use a sharp chef's knife for this step to get uniform small pieces that distribute evenly throughout the salad. Chop the 4 hard-boiled eggs into 1/4-inch pieces, discarding any loose egg whites.
Add the chopped vegetables and eggs to the cooled potatoes. Using a large spoon or your hands, gently fold everything together until the potatoes are lightly coated with the dressing mixture. Be careful not to mash the potatoes at this stage - we want some texture in the final salad.
Combine and Chill for Maximum Flavor
Pour the dressing mixture over the potato-vegetable mixture and gently fold everything together until fully combined. The salad should look creamy but still show some distinct potato pieces. Sprinkle with the 0.25 cup chopped fresh dill and mix one final time.
Transfer the potato salad to an airtight container and refrigerate for at least 2 hours before serving. This chilling time allows all the flavors to meld together perfectly. The longer it sits, the better the taste - I often make it a day ahead for maximum flavor development. When ready to serve, give it one final stir to distribute the flavors evenly.
Pro Tips For Making Mrs Gerry'S Potato Salad Copycat
- BOIL POTATOES UNTIL TENDER: Yukon Golds should break apart with a fork but not turn to mush—aim for 12-15 minutes in salted boiling water. I learned the hard way that undercooked chunks feel like eating wet cardboard, while overcooked ones dissolve into glue. Drain immediately and shock them in ice water for 5 minutes to stop cooking and keep them firm.
- SWEAT ONIONS FIRST: Cook the yellow onion in a dry pan for 8-10 minutes until soft and translucent before dicing—this removes the sharp bite and deepens the flavor. Skipping this step leaves your salad tasting raw and harsh, no matter how much vinegar you add. (Yes, it’s extra work, but the texture and taste make it worth it.)
- DICE CELERY SMALL: Cut the celery into 1/4-inch pieces, not thick matchsticks—this ensures even distribution and prevents dry spots in the mayo. My first few batches had celery chunks that felt like chewing on a toothpick, so I now dice it aggressively. Use a sharp knife and work in batches if needed.
- WHISK VINEGAR INTO MAYO: Mix the apple cider vinegar into the mayo before folding it into the potatoes—this creates a smoother, more stable emulsion that won’t separate later. I used to add it at the end, and the salad would always split into greasy and tangy layers. Do this step in a separate bowl first, then gently combine.
Make-ahead tips for this recipe
Prep Ahead Timeline
The dressing can be made up to 2 days in advance and stored in an airtight container in the fridge. I find this is the most efficient way to prep—simply whisk the mayo, vinegar, mustard, sugar, and spices together and refrigerate.
When ready to assemble, just mix it with the potatoes and vegetables. This saves time on the day of your gathering and ensures the flavors are perfectly balanced. 📅
Potato Prep Shortcut
For maximum efficiency, peel and cut the potatoes 1 day ahead of serving. Store them in cold water in the fridge to prevent browning. When ready to cook, simply drain, boil, and cool as directed.
This step alone saves 30 minutes of prep time on the day you plan to serve. Just remember to dry them thoroughly before adding to the dressing. ⏰
Chilling for Best Results
This salad tastes best after chilling for at least 4 hours, but I recommend making it overnight for maximum flavor development. The longer it sits, the more the vinegar's tanginess mellows into the perfect balance of sweet and sharp.
I often make it the night before picnics or BBQs—it keeps beautifully in a glass Pyrex container with a tight lid. 💫
Portioning for Picnics
Divide the salad into quart-sized glass containers (I use Ball mason jars) before transporting to keep it fresh and prevent sogginess. The glass containers also make it easy to see how much you've got left.
For individual servings, use ramekins or small bowls—this makes it perfect for potlucks where people might want to mix their own portions. 🥫
Make-Ahead for Leftovers
Potato salad actually tastes better the next day! Store leftovers in an airtight container for up to 5 days in the fridge. The flavors continue to meld, and the texture remains perfect.
For a quick lunch, simply reheat gently in the microwave or on the stovetop with a splash of water to restore moisture. It's also fantastic cold in sandwiches or wraps. 💡
Freezer-Friendly Option
While not ideal for texture, you can freeze this salad for up to 3 months in a freezer-safe container. Thaw overnight in the fridge before serving. The potatoes will be slightly softer after freezing, but the flavor remains intact.
I recommend this option only for emergencies or when you know you won't be able to serve it fresh. 🧊

Frequently asked questions
Why does Mrs Gerry's potato salad need to chill before serving?
The chilling time (at least 4 hours) is crucial for two reasons: First, it lets the vinegar's sharpness mellow into a perfect balance with the sweetness. Second, the flavors meld together completely, creating that signature tangy-creamy harmony. Skipping this step leaves the salad tasting flat and underdeveloped.
Can I make this potato salad without mayo?
For a lighter version, substitute 1 cup Greek yogurt plus 0.5 cup light mayo. The texture will be slightly thicker but still creamy. For a vegan option, use vegan mayo and add 1 tbsp lemon juice to mimic the vinegar's tang. Just reduce the vinegar by 2 tbsp to maintain balance.
What's the secret to keeping the potatoes from turning mushy?
Three key steps: 1) Use waxy potatoes (Yukon Golds or reds) and 2) boil them for exactly 10 minutes—no longer! 3) Cool them completely before cutting. Overcooking or cutting hot potatoes releases starch, which makes the salad gluey. Always drain well and let them air-dry for 5 minutes after boiling.
How do I adjust the recipe for a larger crowd?
Double or triple all ingredients while keeping the same ratios. For 12 servings, use 4 lbs potatoes, 3 cups mayo, and 0.5 cup vinegar. The key is maintaining the dressing-to-potato ratio (about 1.5 cups dressing per 2 lbs potatoes). Scale up the vegetables proportionally too—2 onions and 6 celery stalks for the same batch size.
What's the best way to reheat leftovers?
Gently reheat in a skillet over low heat with a splash of water or broth to restore moisture. Microwave in 30-second bursts, stirring between each, until warmed through. For sandwiches, serve cold—the flavors actually improve overnight! Never reheat to a boil, as this breaks down the potato texture.
